J.M. Berger's 2018 book Extremism, a volume in the MIT Press Essential Knowledge series, offers a nuanced introduction to extremist movements, explaining what extremism is, how extremist ideologies are constructed, and why extremism can escalate into violence. Named an Outstanding Academic Title for 2019 by Choice Reviews, and available in six languages. Perspectives on Terrorism: "Elegantly written, the book provides a lucid discussion of a contested concept, with illustrating examples from right-wing, left-wing, and religious terrorism."
Berger's dissertation, The Social Construction of Extremism, expands on the 2018 book. It is available online and will eventually be adapted into a book of its own.
